See the number above my character's health? That is the number representing Bravery.

There are two attacks, bravery attacks and HP attacks. Once you hit your opponent with your HP attack, the damage equals that of your bravery number. So if my bravery is like 2507 and my opponent's health is 2001, one HP attack that I make contact with him will kill him right away, but it takes time to build up your bravery to that number lol.
